Why join us?

It doesn't matter how old you are, or if you are identical or non-identical, same-sex or opposite sex twins, well or ill - all are welcome to join us. Twins can be registered as soon as they are born (and up to the age of 18 - after which they can register themselves) by their parents.

Why are twins so important to research? By studying the differences and similarities between both identical and non-identical twins, researchers are able to to tease apart the effects of nature (genetics) and nurture (environment) on our health and wellbeing.

Our studies look at medical conditions that can affect anyone, such as cancer and diabetes, as well as issues of specific concern to multiple-birth families such as premature birth and twin social and educational development.

By joining us, you become part of something bigger - an amazing Australia-wide community of over 70,000 twins and their families joining forces to make a difference. Membership is free and designed to help twins to thrive, connect and belong.
